This classic steak with a creamy brandy-spiked pepper sauce is a great one-skillet dish. Slideshow: One-Pan Meals
Season the steaks with salt and black peppercorns and let stand for 45 minutes.
In a cast-iron skillet, melt 2 tablespoons of the butter in the oil. Working in batches, cook the steaks over moderately high heat, turning once, until medium-rare, 7 minutes per batch; transfer to a board and let rest.
Pour off all but 2 tablespoons of fat from the skillet. Add the shallots and cook over moderate heat, stirring, until softened, 2 minutes. Add the brandy and cook until most of the liquid has evaporated. Add the stock and cook, scraping up any browned bits, until slightly reduced, 3 minutes. Stir in the heavy cream and simmer until slightly thickened, 1 minute. Remove from the heat and stir in the remaining 2 tablespoons of butter. Season the sauce with salt.
Slice the steak and transfer to plates or a platter. Spoon the sauce on top and serve.
